USD importer: custom normals shading bug.

Removed call to BKE_mesh_calc_edges() after setting
UVs, as this function is already called after setting
polys.  Moreover, the second, redundant call was causing
incorrect viewport shading of previously set custom
normals.  Now also setting the ME_AUTOSMOOTH mesh flag
to enable shading with custom normals.
